The n ism shown consists of a revolving s all driven by a bolt pulley '2' an err; 12 parallel rodsj which as theyrcvol-n \liiilQ under backwardly projecting arms; iixod to the several rammers so as to lift these arms and the rammers, and then pass out from under them,permittingthe rammcrs to fall. 'ioprevent the rammers being thrown up too high, a I stop-rod Z is extended across the top. To pro-- vent the rotativo displacement of the rammers, their upper portions are made square and work in square holes in the uppercrossbar To hold the rammers elevated when not performing the function of ramming, l' provide some suitable device for lockingthc l in their upper position, and preferably at .1 for slightly lifting them to elevate their arms A: above thepath of the operating harsj in order I that as these bars rotate they shall not strike the arms. The preferable device fol-this purpose is that shown in Figs. 1, Qand 2, and consists of a locking pawl pressed toward the rammers by a spring or otherwise, and having means for holding it out of action while the rammers are in. operation. On a transverse shaft G' is pivotally mounted a locking pawl or frameG consisting of tvso arms connected by a bar or blade u, and pressed by springs or otherwise toward the ramuiers. The latter are provided with ribs 1'. ends of which form inclined sh 2). \Vhen in action the pawl. H .s h from the rammers by notched cam-lever ti engaging a pih projecting from the pawl, as

shown in Fig. 2. Upon pulling down this lever thepawl is liberated and presses toward the ribs or on the ram mers. This pressure, however, is insutlieient if the rammers are falling to arrest them, so that they will complete the stroke they are making, when again fully lifted so that the blade u of the pawl passes under the shoulders t", it will act against these shoulders, not merely to uphold the rammers, but by moving entirely provide apair beneath the shoulders to lift the rammers until their arms I; are slightly above the path of the lifting rods j, whercbythe rammers will be held out of action until the operator again pulls down the handle G. This constrnction of locking device for holding the advanta ethat ram more out of action has the to operate it requires no shiil the part of the attendant, quired to make its opera :t with i the completion of the up. tent of the rammers, but: may op it at any ini stant, and its operation will not take e5. I until the rammers complete their l are again lifted to their uppermost 13Gb: n. i This greatly facilitates the work of the an] tendant, whose attention is concentrated on the filling of the matrices in the core-hox beof the locking device may be considerably modified, as for example for pressing the pawl If weights are used the pawl can be thrown out of action by throwing it back until the weight is lifted beyond the Vertical, so that the operating lever G may be omitted, but the construction shown in full lines is deemed preferable.

To provide for punching the vent holes in the cores after they are rammed, and while still held in the core-box, I provide a series of core-wires 0 0 corresponding in number and position to the core box matrices, mounted on a hinged leaf or bar hinged to a vertically sliding horizontal bar H extending beneath the lower bar h, formed with an opening through it through which the rammers may work, and having at its ends a sliding conncetion with the upright frame 0, consisting in the construction shown of stirrup frames h extended around the side frames and having pivoted to their outer ends links or connecting bars q q, which extend down the side frames and are jointed to arms q projecting backwardly, and an operating lever-arm Q projecting forward. ordinarily holds the bar II elevated, but by first swinging the hinged leaf lever Q, the vent wires are caused to descend and punch vent holes in the cores, as shown in Fig. 13.

I will now describe the preferred form of coping-off mechanism. Of course the copes B 15 might be lifted off by hand, but in a long multiple core-box made of metal they are too heavy to be conveniently handled in this way, and I therefore prefer to provide machinery for operating them. I therefore of movable parts J J adapted to engage the opposite ends of the cope B and move it oif obliquely from the drag and from the other cope, and I also provide a pair of moving parts I I adapted to engage the opposite endsof the cope B and lift it 0!? obliquely t0 the drag and away from the other cope. These moving parts might be slides or be otherwise mounted, but I prefer to construct-them as vibratirig arms fixed on oscillatory shafts. The arms J J are both fined on a transverse shaft J mounted in bearings on a frame C'and provided with anysuitable means for oscillating it, preferably a handlever J shown in Fig. l. The arms III are fixed on short oscillatory shafts I I having bearings l at opposite sides of the machine, and p ovided with any suitable means for os- .ng them. The two shafts I must be ated synchronously, and it is preferable to os-t hate them simultaneously with the oscillation of theshaftJ',in order that the arms .1 and i shall simultaneously lift otf the two copes B and ll. To this end I prefer to drive oraol s wire rope uilii'jil to insuro posh tivo motion Sii lliiiil at some suitable point ho fastened to bfiiil pulleys.

The ends of the arms J inlay ilkl lUilllmji fiii in ljillIlGiOilR (lill'ercnt ways to the reapectivo copes, as by olmnpin screwing, pinning, or otherwise. The conntrnction shown ilOWUVfil considered prileriibie, anti consists in forming the coils of tho arms 3 I with groovos or slots adapted to receive and engage the op pofiite @nii projootions if b of tho rosipe -ltii'e coposl. l lzmil arm J is formed at itsoutor and and on its side toward the miiiiilo, with a g oove shown how in Fig. lil.
